What I would like is the ability to (honestly, I'd prefer it if this were the default behavior) link together instances of ingredients and vessels between the various databases and the recipes. Example:

The price on grain just went up. I don't want to manually edit every recipe to reflect this change, I'd rather just change the price of Maris Otter in "My Ingredients" and have that update things.

I changed a piece of hardware in my cooler MLT, altering its thermal profile. If I change that in "My equipment", the change does not push into the recipes.

These little niggly updates are hard enough to make (I'd prefer another panel for editing db entries, or at the VERY least stop making the edit frame modal) as it is, having to make the same edit over and over is enough to make me stop using the features.
